Hi guys, I am a new mac user and i have a ridiculous question to ask and i can't help but think of it. I am very clumsy and i have hit my macbook a few times with my arms. I also have an annoying habit of using my thumbs to hit/strum on my macbook air's aluminium body at the strip of edge surface located at the bottom(i.e area below the bottom of the trackpad and around it). I can literally feel the vibration from my actions sometimes. I am just wondering whether the vibrations/impact of my fingers hitting the aluminium will damage/affect any internal parts e.g. logic board, trackpad or battery? Any feedback/comments are welcomed. Sorry if it was a stupid question and I'm too ocd.
